BOLT-ANCHOR.

Specification of Letters Patent;

Patented Apr. 18, 1916.

' Application filed November 26,1913. Serial No. 803,134.

T 0 all whom it may concern:

Be it known that I, GEORGE I'I. TARLETON, a citizen of the UnitedStates, and a'resident of Plainfield, in the county of Union and Stateof New Jersey, have invented certain new and useful Improvements inBolt- Anchors, of which the following is a specification, taken inconnection with the ac companying drawings, which formapart of the same.

My invention relates to bolt anchors to secure articles to a wall orother support which may be of stone, concrete, terra cotta, or any othermaterial.

More particularly my invention comprises a bolt anchor having expansiblemembers pivoted on a body member. I

My invention further includes a face plate or escutcheon, carried by thebody member, which will cover the opening in the wall or other supportand give a handsome effect to the work.

My invention further comprises a bolt anchor having pivoted expansiblemembers and a bolt and nut, the parts being so formed that when onceassembled they can be readily handled, packed and shipped, withoutbecoming disconnected or running any danger of these different elementsmoving from their cooperating positions.

In the accompanying drawing showing an illustrative embodiment of myinvention and in which the same reference numerals refer to similarparts in the several figures: Figure 1 is a longitudinal verticalsection through the bolt anchor the cooperating bolt being shown in sideelevation; Fig. 2 is a longitudinal vertical section similar to Fig. 1showing the bolt anchor mounted within an opening in the support andexpanded, the article to be supported being omitted for the purpose ofclearer illustration; Fig. 3 is a plan view of my bolt anchor; Fig. 1 isa transverse vertical section substantially on the line 44 of Fig. 1;and Fig. 5 is a face view showing the face plate covering the raggededges of the opening which is shown in dotted lines.

In the illustrative embodiment of my invention shown in the drawing 1 ismy improved bolt anchor comprising a body member 2 to which are providedthe rigid expansible members 3 and 4 by the pivot pins 5-5. The interiorsurfaces 6-6 of these pivoted members 3 and 4 flare slightly from thebody member 2 toward the other end or toe 7. Within the flaring'opening'16, so formed, I mount any suitable expansion means such as theconical nut 8 which cooperates with the bolt 9. Preferably, though notnecessarily, the nut is substantially square in cross section tocooperate with the opening 16 of that contour. Of course, it is to beunderstood that any other suitable contour may be used, it being simplynecessary to hold the nut from rotation andpermit its longitudinalmovement to expand the pivoted expansible members 3 and 4: as shown inFig. 2. I preferably provide each of these expansible members 3 and 4with a heel 10 which will engage with the bolt and in that manner form aunitary structure which can be handled, shipped or stored readilywithout any of the parts becoming accidentally disconnected ordisarranged from their operative position. In Fig. 2 the expansion issomewhat exaggerated.

The opening 11 in a wall, or other suitable support 12, is concealedpreferably by the face plate or escutcheon 13 which is preferably,though not necessarily, carried by or formed integral with the bodymember 2. The use of this face plate 13 not only insures the boltanchor, being located at the proper depth in the wall but also serves tohide the ragged edge 14 of the opening ll-and give a handsome efiect tothe work. I may also provide thetoe of the expansible members 3' and 4:with lips 15, 15 to more readily engage with the support 12. Having thusdescribed this invention in connection with several illustrative embodi-I ments thereof to the details of which I do, not desire to be limitedexcept as defined by the scope of the appended claims, what is claimedas new and what is desired to secure by Letters Patent is set forth inthe following claims:

1. In a bolt anchor the combination of an escutcheon plate to cover thehole, a body member carried by the escutcheon plate and adapted to fitinto the hole in the wall or other support, expansible members pivotedto the body member and adapted to extend farther into the hole, andmeans to expand the expansible members, the escutcheon plate hiding theraw edges of the hole.

2. In a bolt anchor the combination of a body member, eXpansible memberspivoted to the body member and having a heel to contact with the bolt tolimit the outward throw of the pivoted expansible members, a nut, and abolt to cooperate with the nut find with the heels of the expansiblememers.

3. In a bolt anchor the combination of a face plate provided with arigid body member, expansible members pivoted to the rigid body memberand having a heel to contact with the bolt to limit the outward throw ofthe pivoted expansible members, a nut, and a bolt to cooperate with thenut and with the heels of the expansible mem- 15 bers.
